I would like to know if are extracted in the results summary tables with the m-factors in the case of Response Spectrum Analysis with m-factors approach and where exactly are the structural members classified as ductile or brittle in the output.

Many thanks in advance.

I have created some charts in excel if you'd like to take a look.

I have to point out that the strain hardening parameter of 0.04 is out of the range from 0.005 to 0.15 which are recommended.

Dear Zoi Gronti,


By modifying the parameters of the material, setting the specific yield stress (fy=328,6 MPa) and choosing a strain hardening parameter high enough at 0.04 the curve matches that of the experiment, but continue to load over 300kN, where the fracture occurs according to the paper ...

If someone faced similar situation and problems, any help and advices would be appreciated.

Hi,

I have indeed increased and experimented with these parameters for more than two weeks and noticed that affect the results. I achieved a yield to 285 kN, but at a high drift 6%..

One last question. The Fy parameter refers to yield and not to ultimate strength? If i set this to fu=490 MPa i'm ...

Dear Seismosoft team,

I've been trying for a long time to verify a research study on steel brace with intentional eccentricity and I really haven't been able to do it.

It's a simple model of a steel brace with a cross-section CHS114.3x3.5 subjected to cyclic loading.
Steel: fy=328 MPa & fu=490 ...

I forgot to mention that as material I chose steel S235 Ramberg-Osgood with Yield strength Fy=235000 kPa

Dear seismosoft team

I noticed that the elastic properties of a cross section e.g. CHS114x3.2 mm calculated with seismostruct deviate from those calculated by hand.

The modulus of elasticity for steel is 210x10^6 Kpa, the other properties depend on the cross section, the units in kN & m and ...

I'm glad you solved it.
I would just like to say that your direct response to user requests and questions is impressive!
congrats
